Every time you consider that not holding your opinion is “objectively stupid” you should stop a moment to reflect what those words mean.
Your subjective opinion is that the democrats are the only viable alternative to Trump and so everyone must support them because the alternative is worse.
It is a valid opinion, but it is not by far an objective truth.
Another subjective opinion is that the entire bipartisan system is a single entity focused on maintaining the status quo, and that real change is not possible by voting democrat (or even by voting at all).
It is objectively true that any effort towards strengthening the democrats is not spent elsewhere, and it is also an objective truth that there have been multiple democrat presidents in the last few decades and have been unable or unwilling to effect change to a degree that satisfies leftist voters.
My European perspective is that defending corporate right as an alternative to fascism is an acceptable emergency measure while there are big credible efforts for large scale reforms to at least have a real left voting option, but it’s not by far a solution to the problem.
Maybe instead of calling “useless idiots” all those who didn’t vote for trump, your energy might be better spent trying to build a common platform with them, at least if you want them to vote on the next election.
And if you want that common platform to be the democrats, they will have to change a lot.

From Europe, I see the republicans as a stick and the democrats as a carrot.
You are angry because people refused to vote against the stick, and I understand why, it makes sense.
At the same time, it’s easy to understand that there are people against the carrot&stick system, and I wouldn’t consider them useless idiots for not voting for the carrot.
Also, the carrot is fucking stale.

Yes, grok is a verb coined by Heinlein in Stranger in a strange land, which is a great book in my opinion.
